Stephen M. Kohn, with 38 years of experience, was peer-review rated by the National Law Journal as one of the 50-top Plaintiff’s Lawyers in the United States, the only whistleblower rights lawyer to achieve this distinction.

In 1988 he helped found the National Whistleblower Center, where is currently serves, pro bono, as Chairman of the Board. He is the author of the first legal treatise on whistleblowing and is the world’s most published author on whistleblower protection. His most recent book is Rules for Whistleblowers: A Handbook for Doing What’s Right (Lyons Press 2023).

Kohn has spearheaded several of the largest whistleblower cases in the U.S. and internationally. He is known for his successful strategies, leveraging whistleblower protection and reward laws, many of which he played a significant role in authoring.

Key Whistleblower Legislation

Steve helped draft key whistleblower legislation and regulatory rules, including those incorporated into the following:

In addition to being added to the inaugural list of Top 50 White Collar Crime Trailblazers, Kohn has been a major contributor to whistleblower law, including the following:

  • Chief attorney in Dodd-Frank Act whistleblower case finding restrictive nondisclosure agreements illegal under U.S. securities laws.
  • Successfully represented key Swiss banking whistleblowers who triggered the historic prosecutions of Swiss banks (resulting in over $15 billion in sanctions, fines and settlements).
  • Successfully represented first nationally recognized FBI whistleblower, causing President Clinton to order the Attorney General to establish whistleblower protections for all FBI employees.
  • Argued case establishing nationwide precedent under the First Amendment recognizing the right of federal employees to publicly blow the whistle on their employing agencies.

Watch how Stephen and his client Bradley Birkenfeld brought Swiss banking giant UBS to it’s knees, landing them one of the largest whistleblower rewards in history of $104 million.

Notable Cases

  • Howard Wilkinson - Money Laundering Whistleblower
    $2 Billion Recovered for Victims

    Wilkinson confidentially blew the whistle on a $230 billion Russian money-laundering scandal that moved rubles out of Russia, converted them to dollars at the Estonian branch of Danske Bank, and then moved the dollars to New York.

  • Foreign Corrupt Practices Act - Novartis Greece Bribery
    $300 Million in Sanctions

    Our client exposed a foreign corruption and illegal drug marketing bribery scheme, requiring Novartis to pay over $300 million in sanctions and fines to the U.S. Securities Exchange Commission (SEC) and the Department of Justice (DOJ).

  • Whistleblowers 2176176 and 77 - Tax Whistleblowers
    $17.4 Million Joint Award

    This case set the national precedent covering tax whistleblowers whose work with the Justice Department resulted in criminal convictions. After two significant victories in Tax Court, the whistleblowers obtained $17.4 million in rewards.

Stephen M. Kohn

“Stephen Kohn has dedicated his life to supporting whistleblowers and uncovering wrongdoers. I admire his tireless efforts…”

Bradley Birkenfeld - Largest Whistleblower Reward in History

“The only lawyer on my side was Steve Kohn. He was as smart as they come and feisty as a pit bull. Steve was convinced the government owed me a fat reward, and he was going to get it, or die trying.”

“An absolutely first rate lawyer. . . keenly interested in utilizing the law as a rational instrument of social change and improving the quality of life for the weak, the poor and the unpowerful.”

A. Leon Higginbotham, Jr., Former Circuit Judge, U.S. Court of Appeals for the Third Circuit

“[Steve Kohn] is an outstanding person, with a very keen mind, a true gift for research, an extremely capable writer, and an eloquent speaker.”

Howard Zinn, Author, A People's History of the United States
Roger Wensil - A Client of Michael Kohn

“I want to try to express my feelings of gratitude for what you are doing for me, but I’m not sure that words will do the job . . . The bureaucrats almost won; not because they were legally right, but rather, because they have the power and influence to be able to crush any resistance . . . You are rendering a great service, not only to individuals like myself, but to our country a well.”

William Sanjour

“Steve Kohn is the nation’s outstanding whistleblower lawyer.”

Linda Tripp

“I couldn’t have navigated the shark invested waters whistleblower face without the passion, dedication, determination, and brilliance of my incredible attorneys.”

“…the three co-founders of the National Whistleblower Center, these are important names, Stephen Kohn, Michael Kohn, and David Colapinto, thank you so much for all that you do, they broke the mold with these visionaries and we are all better for it.” – National Whistleblower Day, 2018

Jane Turner Thumbnail

“When I had to blow the whistle it was very very difficult. I was lucky I had my daughter and I was lucky I had Stephen Kohn in my life. . .he [Stephen Kohn] dragged me across the finish line . . . he stayed with me, he kept me going . . .”

40 Years of Accomplishment

Kohn is one of the most actively involved whistleblower attorneys in the world, focusing on issues of serious public importance.

In recognition of the growing importance of whistleblower litigation, The National Law Journal named the whistleblower attorney and advocacy law firm of Kohn, Kohn & Colapinto as one of Top 50 plaintiff’s Law Firms in the United States. The firm’s partners were officially named as among “America’s Elite Trial Lawyers.” In its September 29, 2014 article, “Elite Trial Lawyers: The 50 Leading Plaintiff’s Firms in America,” the National Law Journal named Kohn, Kohn & Colapinto as one of the firm’s “doing the most creative and most important work in the courtroom.”
